Atrial cellular electrophysiological changes in patients with ventricular dysfunction may predispose to AF [PDF]

open access: yes, 2009
<b>Background:</b> Left ventricular systolic dysfunction (LVSD) is a risk factor for atrial fibrillation (AF), but the atrial cellular electrophysiological mechanisms in humans are unclear.

Pulmonary Embolism—A Century of Progress

open access: yesANZ Journal of Surgery, EarlyView.
Reviews a century of progress in the diagnosis, prevention, and management of pulmonary embolism; from the first successful surgical embolectomy in 1924 to advanced imaging, pharmacological thromboprophylaxis, and treatment. In the 21st century, advances include catheter‐directed thrombolysis or mechanical thrombectomy under decision‐making guidance of

Agreement between cardiac cycle time intervals and myocardial velocities measured by automated analysis of color tissue Doppler cine loops and by manual tracing of spectral pulsed‐wave tissue Doppler waveforms of sheep fetal heart under normal and pathological conditions: An experimental study

open access: yesActa Obstetricia et Gynecologica Scandinavica, EarlyView.
Automated cTDI in sheep fetuses provided reproducible measurements of myocardial velocities and heart rate that align well with manual pulsed‐wave TDI. For cardiac cycle duration metrics, the two modalities are not interchangeable. These findings support that automated cTDI is well suited for longitudinal assessment under both physiological and ...

Cardiac Device Algorithms for Optimal Outcomes in Patients with Sick Sinus Syndrome [PDF]

open access: yes, 2013
Sick sinus syndrome (SSS) is a relatively common chronic condition affecting the electrical conduction system of the heart. In the absence of any reversible cause of SSS, the most effective treatment is implantation of a permanent pacemaker to maintain ...

Prenatal imaging phenotypes and outcomes of umbilical‐portal‐systemic venous shunts in singleton and twin pregnancies: A historical cohort study

open access: yesActa Obstetricia et Gynecologica Scandinavica, EarlyView.
This retrospective cohort compared umbilical‐portal‐systemic venous shunts in singleton and twin pregnancies. Type III was the most common subtype in singletons, whereas Type II was the most common in twins. Fetal growth restriction was more frequent in twins, but primary structural anomaly rates were similar.

Positional cyanosis reveals platypnea-orthodeoxia-syndrome

open access: yesRespiratory Medicine Case Reports, 2019
Platypnea-orthodeoxia syndrome is a rare cause of dyspnea, which presents upon standing and resolves when supine. Etiology is multifactorial with a functional component and an anatomical shunt. The most commonly reported shunt is an atrial septal defect,

Sudden Unexpected Postnatal Collapse: A Retrospective Cohort Study Describing Incidence, Risk Factors and Role of Perinatal Transition

open access: yesActa Paediatrica, EarlyView.
ABSTRACT Aim This study aimed to investigate the incidence, risk factors and possible aetiology of sudden unexpected postnatal collapse (SUPC), a potentially fatal yet poorly understood event. Methods In a retrospective cohort, patient records from 483 284 infants born in Stockholm, Sweden, between 2002 and 2022 were screened for SUPC‐related diagnoses.

Combined perventricular closure of ventricular septal defect and atrial septal defect via lower ministernotomy

open access: yesJournal of Cardiothoracic Surgery, 2018
Background Minimally invasive approaches such as perventricular closure of ventricular septal defects (VSD) have been applied for the surgical correction of congenital heart defects in order to avoid disadvantages related to median sternotomy with a ...

Echocardiographic assessment and percutaneous closure of multiple atrial septal defects [PDF]

open access: yes, 2004
Atrial septal defect closure is now routinely performed using a percutaneous approach under echocardiographic guidance. Centrally located, secundum defects are ideal for device closure but there is considerable morphological variation in size and ...
